Black night shade

BLACK NIGHT SHADE Solanum nigrum, L., Solanaceae, is a common weed in gardens and waste places. The whole plant is toxic due to the occurrence of the alkaloid solanine, giving the same symptoms as Bittersweet. 

Even if they do not react as drastically to extreme environmental temperatures, many insects and animals become inactive during at least part of the day. During cold nights, snakes, lizards, and other small animals hide in burrows where temperatures do not fall as low as outside. Insects such as the predatory tiger beetle hide in the shade (Figure 6.15.2) during the day when surface temperatures on the black sandy beaches of New Zealand, where it lives, reach 70°C (Molles, 1999).
